How do I give the protons, electrons, and neutrons for an isotopes.

1 answer:

3 0

For an isotope of a certain element, only the number of neutrons are changed, the number of protons stays the same because if you change the proton it would mean that it is a different element already. The number of neutrons is calculated from the number shown in the isotopes. That number represents the total protons and neutrons.

Iodine-127 : protons = 53, neutrons = 74
Iodine-126 : protons = 53, neutrons = 73
Iodine-128 : protons = 53, neutrons = 75

Anni [7]

Answer:

Explanation:

1. A student mixes baking soda and vinegar in a glass. The results are shown at left. ... Yes I do belive that new substances are being formed because there is a chemical reaction between the baking soda and vinegar turning it into a bubbly substances instead of a powder and liquid.

9. For each reaction listed, identify the proton donor (or acid) and the proton acceptor(or base).

Talja [164]

Answer:

Explanation:

conjugate acid, based on Brønsted–Lowry acid–base theory, is a chemical compound that is formed by the reception of a proton by a base

a. CH₃COOH + H₂O ⇌ H₃0⁺ + CH₃C00-

Acid <> CH₃COOH

Base <> H₂O

Conjugate acid <> H₃0 +

Conjugate base <>CH₃C00-

b. HCO₃ + H₂O ⇌ H₂CO₃⁻ + OH⁻

Acid <> H₂O

Base <> HCO₃

Conjugate acid <> H₂CO₃⁻

Conjugate base <>OH⁻

C. HNO₃ + SO₄²⁻ ⇌ HSO₄⁻ + NO₃⁻

Acid <>HNO₃

Base <>SO₄²⁻

Conjugate acid <>HSO₄⁻

Conjugate base <>NO₃⁻

A Bronsted acid is reffered to as a proton donor while a Bronsted base is a proton acceptor
